SestoSenso driver was also updated.. if there are any users out there, please report back if it works since I don't have the hardware.

Hi Jasem,

Unfortenately the new driver doesn't work for sesto senso2. The basic problem is that when one requests all parameters about MOT1 the response string is too long and gets truncated (most likely in the focusser itself, not in INDI). In primalucelabcommandset.cpp, this happens for the json command on line 450. This makes the driver crash. The solution should be to modify the json request so that only the desired parameters are returned. With the new structure it is not clear to me how that should be implemented.

The json command on line 736 will most likely cause the same problem but I can't test this since I don't have an ARCO device.

Thank you for the update Camiel. I pushed an update to increase receive buffer, can you please git pull and see if this helps?

Another Sesto Senso 2 user here, suffering from the same issue. I am totally illiterate when it comes to these thing so I would need a lot of help and guidance if I were to try and be of any help in solving this.

Anyone tested after the update to GIT?

I did : using an Esatto 3 device, which embeds the latest firmware (named as 03-03-07), and the indi_esatto_focus driver. Everything (but the temperature report) is OK. For temperature, I am not sure the issue is software-related, maybe my external sensor has some trouble. But all the main functionalities are up and running.
However, I have not tested with a SestoSenso type of focuser.
Thanks a lot.

Hi Jasem,

With sesto senso2 I still have the problem that the driver crashes. This is what I find in the log file:

As you can see the last json response is truncated. I don't think this is caused by the indi driver. The fixes I posted before worked around this problem for SPEED and ABS_POS
by requesting only the information (ABS_POS or SPEED) that was really needed instead of requesting all information on MOT1 and extracting in the indi driver the parameters of interest.
I think this is needed here as well.

Hope this helps,
Camiel

Ok I would need remote access to eliminate any other possibilities

Hi Jasem,
There are two things that need to be changed for sesto senso2 to work. First, the method to select one of the motor presets should be:

bool SestoSenso2::applyMotorPreset(const std::string &name)
{
return m_Communication->command(MOT_NONE, {{"RUNPRESET", name}});
}

And the method getting the motor settings works when it reads as follows:

bool SestoSenso2::getMotorSettings(MotorRates &rates, MotorCurrents &currents, bool &motorHoldActive)
{
//json jsonRequest = {{"req", {{"get", {{"MOT1", ""}}}}}};
json jsonRequest = {{"req", {{"get", {{"MOT1", { {"FnRUN_ACC",""}, {"FnRUN_DEC",""}, {"FnRUN_SPD",""}, {"FnRUN_CURR_ACC",""}, {"FnRUN_CURR_DEC",""}, {"FnRUN_CURR_SPD",""}, {"FnRUN_CURR_HOLD",""}, {"HOLDCURR_STATUS",""} } }}}}}};
json jsonResponse;

if (m_Communication->sendRequest(jsonRequest, &jsonResponse))
{
jsonResponse["get"]["MOT1"]["FnRUN_ACC"].get_to(rates.accRate);
jsonResponse["get"]["MOT1"]["FnRUN_DEC"].get_to(rates.decRate);
jsonResponse["get"]["MOT1"]["FnRUN_SPD"].get_to(rates.runSpeed);

jsonResponse["get"]["MOT1"]["FnRUN_CURR_ACC"].get_to(currents.accCurrent);
jsonResponse["get"]["MOT1"]["FnRUN_CURR_DEC"].get_to(currents.decCurrent);
jsonResponse["get"]["MOT1"]["FnRUN_CURR_SPD"].get_to(currents.runCurrent);
jsonResponse["get"]["MOT1"]["FnRUN_CURR_HOLD"].get_to(currents.holdCurrent);
int tmp;
jsonResponse["get"]["MOT1"]["HOLDCURR_STATUS"].get_to(tmp);
motorHoldActive = ( tmp == 1 );
return true;
}
return false;
}

Thanks! I pushed the changes as you suggested, can you please verify now?

Hi Jasem, it works now.

Regards,
Camiel

Is there someone who could help aid me in adding these fixes to my Astroberry installation? My Sesto Senso 2 is just sitting there, unused.
